Currently dealing with an Outlook issue for one of my clients. Traffic forwarding is via PAC file URL. When users open up an email with Outlook, no images embedded in the email are displayed. When we point user to their local proxy, restart Outlook, users can see the images in the emails. But when user Internet traffic is routed to Zscaler via Pac file URL, no images displayed in the emails.
I believe Zscaler is configured correctly. I suspect some type of incompatibility between Outlook and PAC file URL used to route user Internet traffic to Zscaler.
Any suggestions on how to resolve this matter are greatly appreciated.
